The vacuum interrupter (VI) and the vacuum switch (TVG) differ considerably in velocity of electrical strength recovery, value of electrodes erosion, etc. It depends on difference in discharge types. To level these values it is offer in the paper to close the current I0 through TVG before the VI electrodes motion under it it's this value exceeds initial current on DeltaI (DeltaI-current, DeltaI/I0 ~5divide10middot10-2). Surplus DeltaI-current flows through VI but in opposite direction. In the process of electrodes moving apart, DeltaI-current in VI falls down to zero, with time constant tau = L/R, where L, R-inductance of circuit (VI-TVG) and resistance of TVG gap, correspondingly. It makes possible to fast recovery electrical strength of gap between contacts, to reduce considerably erosion of electrodes and voltage of DeltaI-current. On the final stage of the discharge of counter current battery recovery the vacuum strength of TVG gap. Such way of current breaking makes it possible to break direct currents effectively with high power. It is consequence of the combined opening switch technology based on vacuum interrupter and plasma erosion switch","PeriodicalId":369861,"journal":{"name":"2006 International Symposium on Discharges and Electrical Insulation in Vacuum","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114793776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The discharge tube was made of Pyrex glass with outer diameter of 30 mm. A 4-turns coil was wound on the tube and RF power up to 100 W with frequency of 13.56 MHz was input to initiate a discharge. The luminance of the xenon discharge drastically changed depending on the pressure. When decreasing the pressure from 6.65 kPa to 26.6 Pa, the luminance basically had a tendency to decrease except of the case when the pressure was around 39.9 Pa; the luminance was suddenly increased up to 28,000 cd/m2 at 39.9 Pa, whereas it was about 2500 cd/m2 at 133 Pa. The emission spectrum at 39.9 Pa showed a continuum ranged over the visible region, on the other hand, atomic and ionic line spectra were dominant at 133 Pa. At 39.9 Pa, the discharge color was white and general color rendering index was 90, which is enough for the general lighting. It is thought that the wide range visible continuum is attributed to the ion-electron recombination radiation and results in the increase in the luminance. The detailed investigation of the mode change mentioned above through the measurements of the plasma parameters such as electron density etc. is now under progress","PeriodicalId":369861,"journal":{"name":"2006 International Symposium on Discharges and Electrical Insulation in Vacuum","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123877152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A point electrode with a CR high-pass-filter at one end of a long coaxial cable was faced on a surface of 3 mm thick water layer on the grounded-plate in a low-pressure chamber. When the cable and a coupling condenser in the filter were charged and then directly grounded at the other end of the cable, repetitive discharges propagated from the point electrode along the water surface with a very high frequency. In the test of an optical study, transient discharge light was observed using a gated image intensifier under gas pressures of 0.1 MPa and 0.02 MPa in air. Several discharge channels with branches propagated from the point electrode in 0.1 MPa, whereas glow-like discharges rapidly spread along the water surface in 0.02 MPa with a very high propagation speed. However, reaction speed of indigo carmine molecules in water in 0.1 MPa became higher than that in 0.02 MPa in a decolorization test. We concluded that active species produced by the surface discharge under atmospheric pressure had an important role for the decomposition of the indigo carmine molecules in water","PeriodicalId":369861,"journal":{"name":"2006 International Symposium on Discharges and Electrical Insulation in Vacuum","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123361940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
